Perhaps with some trepidation, a pair of dog owners led their respective pets towards an unwitting family reunion. Apparently, it had been three months since Harper the puppy had found her forever home, and the young animal had not clapped eyes on her mother since. But how would the retrievers react? In fact, would they even remember each other at all?

Ever since dogs were first domesticated, humans and canines have happily spent their lives together. And this has proven to be a mutually beneficial arrangement, since both species get love and affection from each other. Indeed, our four-legged companions are not given the honor of being called man’s best friend for nothing. But dogs and humans also share a specific behavioral trait: like us, dogs are usually social animals that crave companionship.
